Japanese Clay Coins book

Japanese Clay Coins - Maboroshi - Japanese Ceramic Coinage - Circa 1945

The mysterious Japanese ceramic coins (Japanese clay coins) from 1944–45 provide a snapshot of a brief and fascinating part of Japanese numismatic history – the fragile link between war and peace in Japan.

‘Maboroshi’ is a Japanese term to describe these coins and translates as the phantom. These small ceramic coins (clay coins) are undoubtedly mysterious, and like a ghost in the night, as soon as they appeared, they were gone. Mystery surrounds their existence, use and destruction at war’s end.
This Japanese clay coin Book tells the story – the trials and tribulations of these coins from their concept to production and destruction. This work is a culmination of years of research and draws on information pieced together from an unpublished, hand-written manuscript; video recordings of first-hand accounts; information provided by coin dealers, ceramic specialists and experts in Japanese numismatics; records and information provided by Japan Mint, Osaka. Buy now>

What is Japanese Invasion Money?

Japanese Invasion Money (JIM) is the currency that was issued by Japan to replace local currencies of areas they had occupied, defeated or had plans to, in World War II. JIM was officially known as Southern Development Bank Notes. 

The main purpose of introducing the new currencies was to cripple the economies of these areas as with the introduction of JIM their own currency was rendered worthless. Japanese troops strongly enforced the use of their new ‘mickey mouse’ or ‘banana’ money and harsh penalties, including death, were applied for people caught using non-JIM currency.

Japan’s prime minister of the time, Matsuoka Yosuke and the Government had a vision of a united Asian power led by Japan. This was to be known as the Greater East Asia Co-Prosperity Sphere. This concept, similar in theory to today’s European Union, would be independent of the West and be a force led by Japan for the greater prosperity of Asians. Although Japan was promoting prosperity for all Asians, they still had a distinct ‘pecking order’ with the nation’s allies.

By the end of World War II, invasion monies were issued for: Philippines; Burma (Myanmar); Malaya (Malaysia, Singapore); the Dutch East Indies/Netherland Indies (Indonesia) and Oceania (British New Guinea, the Solomon Islands , the Gilbert Islands and Australia).

Throughout WWII, JIM notes became souvenirs of returning soldiers who brought back captured notes to Australia and used these as proof of the intended invasion of Australia by Japanese forces.

For the avid collector, JIM notes are an ideal item to make into a collection. You may start with just collecting the notes that relate to your chosen country or you can complete a standard set collection with a note to represent each denomination and region. For the more-serious collector, you can add to this examples of prefixes, variations, propaganda notes, flyers and coins.

Netherlands East Indies

The design of the Netherlands East Indies Peace gulden has been inspired by The Japanese Government coins, issued in World War II.

The Arjuna illustration was hand-drawn by Brisbane-based designer, Gregory Hale. He used an original Japanese Government 10 sen coin as his reference to faithfully recreate the illustration.

Arjuna is a character from a traditional Javanese wayang kulit (shadow puppet) fable. Japanese coins featuring Arjuna were minted in 1943 and 1944. Many of these mysterious coins were lost at sea en route to Java, making them rare and valuable to collectors.

Size: 34 mm Ø. Includes coin capsule.
